Chapter 1824

There was nothing wrong with the insects just now. Why don't you let yourself go now?

He hesitated and asked, "what do you say?"

"Alas, there's only one way. I'll go and I'll get you alive so that you won't be in danger."

Chang sun sighed and said something helpless.

Huh?

Du Gou frowned.

Wait here with this boy?

"No, I'll go. I have to go."

Du Gou waved his big hand and refused.

"Hey, hey, I haven't spoken yet. It's good for you two. You're all wrapped up."

Chumo stands up and spreads out his hands, showing an air of fluidity.

"Iron bull, you've been to heaven once. What are you fighting for?"

Du Gou was a little unhappy and stared. Although he didn't have Chumo Zhuang, he didn't want to give in at all.

"You're not right. It's not good to take the truth alone. I had a day, but it doesn't affect the competition for welfare."

Chumo stretches his arms tightly and doesn't want to give in at all. It seems that this guy has completely inherited Yaojin's banditry, but he says he will solve the problem by force.

"All right, don't make any noise."

Zhang Feng stood up and waved to stop the three people's mischievous behavior: "isn't it just doing an experiment? What's going on?"

When the voice fell, the three people lowered their heads angrily. It seemed that they were not satisfied, but now Zhang Feng was a big rich man. They didn't dare to say anything. Even Chumo was soft. His tense arms hung down and looked at Zhang Feng with dissatisfaction.

"Feng Zi, who will finish this step?"

Chumo holds his head high and seems very confident.

"You want me to say."

Zhang Feng glanced at the crowd. Finally, he looked behind Du Gou and smiled: "just Du Gou. You've all taken benefits. This guy has nothing."

As soon as the voice fell, Du Gou suddenly looked up and stared at Zhang Feng with a pair of eyes, as if there were water swirling: "Feng Zi, thank you very much. Unlike these two guys, you know how to bully me."

While talking, he glanced at Chumo's elder sun Chong, who came back with a sad look.

"All right, don't be sour here. Get ready to start."

Zhang Feng waved and didn't care about these details: "big cake, go and put the copper wire on the battery into the two holes just drilled by Ma Zhou. Remember to put the copper wire into the water."

Du Gou frowned. He saw that the insect touched the copper wire just now. Now he still has to touch it. He hesitated a little, but he thought he could rise to heaven after the experiment. These pains should still be tolerable.

His heart crossed, he slowly stretched out his hand and grabbed the copper wire. At this moment, a pain of ant bite came, which made him want to throw away the copper wire immediately. But when he thought about it, he still inserted the copper wire straight into the cardboard hole until it disappeared into the water.

"Feng Zi, is it ok now?"

Du hook put down the copper wire and touched his slightly painful finger.

"OK, you stand aside and have a rest."

Zhang Feng waved at will, but his eyes focused on the cardboard, as if he couldn't move it.

This is a ceramic jar. He can't see the inside clearly. He can only observe it through the cardboard on the surface. Therefore, he doesn't dare to take it lightly now.

"Teacher, what should I do now?"

The horse came forward and stared at the cardboard like Zhang Feng.

"One word, wait."

Zhang Feng said faintly that since we can't see the situation inside, we can only see whether hydrogen is produced according to the situation of the paperboard. If hydrogen is produced, there will be bubbles near the copper wire in the water. At that time, these bubbles will jack up the paperboard, which can be seen from this phenomenon.

Ma Zhou and Hao Chujun nodded vaguely. This was the first time they came into contact with this kind of thing. They could only obey their mentor's orders. Of course, they also wanted to learn some new knowledge from it.

Chumo and Chumo also gathered around with curiosity. The three of them had no interest in the experiment, and even wanted to end the damn experiment early so that they could go out and continue to take the hot-air balloon. However, they couldn't help being curious. After all, they were young people, full of curiosity about emerging things.

Everyone stared at the cardboard seriously. The laboratory was silent. It was strange. There was no sound except the breath of everyone.

After about a incense burning time, a scream rang through the whole laboratory.

"Move, move."

Chumo points to the cardboard and stares at it as if he hadn't met.

"What's the noise?"

Zhang Feng shouted with a slap and didn't give a good face: "it's just moving. What's so noisy?"

With that, he looked at Ma Zhou, who was stunned on one side: "go and get the silk and get ready to inflate."

"Oh, oh."

Ma Zhou had some hindsight. He didn't forget to glance at the cardboard before he hurried out of the door.

After a while, Ma Zhou came back with silk. He took silk in his hand and gasped: "mentor, silk has been taken back. What should we do now?"
